Abstract

This study were conducted in survey method. Four stations were established with three replication of each sampling station. It revealed that oil content in water ranged from (0.4391 – 0.7973) ppm. The highest epiphytic diatom density on the seagrass leaves oppeared in station 4 which accounted 366 ind/cm2, while the lowest 132 ind/cm2 found in station 2. During the study, epiphytic diatom species most commonly found are Isthmia sp, Navicula sp, Skeletonema sp, Ulothrix sp, dan Synedra sp. Statistical analysis showed the oil content and epiphytic diatom density correlation were weak with coefficient of (0.05)Key words : Rupat Utara Water, Oil Content, Epiphytic Diatom

Abstract

Disaster-prone conditions in Indonesia cause a large number of impacts experienced such as casualties, damage to infrastructure and other vital facilities. With this impact, people's knowledge and understanding of geological natural disasters and mitigation efforts need to be educated early on. Mitigation is a series of activities carried out to reduce disaster risk and is included in the initial stages of natural disaster management. Of course the activity of providing geological disaster information and its mitigation is one of our responsibilities as geologists in academia to provide knowledge and understanding to the community, and one of the targets is early childhood or elementary school students. The output of this activity is to increase the capacity of the community, especially elementary school students, to understand early on the importance of disaster mitigation in efforts to reduce or minimize losses due to geological disasters. This activity was carried out by lecturing and simulation methods of a number of geological disaster events, the introduction of prepared disaster bags including the introduction of K3 (Occupational, Safety and Health).

Abstract

The development of scientific subjects in geography at the secondary school level has an impact on knowledge about geology, including rocks and their formation processes, the origin of the earth, to how to plan urban planning in a geographic information system. Geography books generally refer to the international earth science curriculum, making it very difficult for high school students to understand it. The main problem revealed by teachers and students who are interested in OSN in the field of earth is that the material being contested is quite complex. The basic problems of geology, spatial planning and disaster become national and even global issues. Through the Community Service Program activities, the Faculty of Engineering in this case is represented by a team of lecturers from the Geological Engineering Study Program offering Student Centered Learning methods to facilitate understanding of the National Science Olympiad material in the field of Earth Sciences. Besides that, it can also motivate and competitiveness to take part in competitions, especially for students of SMA Negeri 8 Gowa. The purpose of community service activities is to: a) Provide basic geological knowledge as part of earth science; b) Providing knowledge of Indonesian geology; c) Provide material tested in the national earth science olympiad; d) Provide the practice of identifying minerals and rocks, geological structures, fossils, and topographic map readings.

Abstract

Water as a natural resource is the most important part for humans to continue their life. One example of the vital role of water resources for human activities is to fulfill food through agriculture and plantations. The availability of water needs for agricultural productivity is certainly an important study to maintain supply capacity and avoid crises in agricultural and plantation foodstuffs. As mandated by the Water Resources Law, the utilization of water resources is aimed at sustainably utilizing water resources by prioritizing the fulfillment of the basic needs of the community fairly. For the sake of the continuity of human life, water resources must be managed properly by paying attention to and protecting the environment. Almost not all the agricultural and plantation areas in the Planting area have irrigation channels that utilize surface water. Consequently, agricultural production does not reach maximum results, because its water needs are very dependent on rainwater. On the other hand, even though there is an irrigation network, there are areas where the availability of water is not sufficient, so that farming activities of farmers cannot get maximum results. This limitation causes farmers to depend on surface water supply, especially during the rainy season so that problems such as prolonged drought can have fatal consequences. One of the efforts to improve agricultural irrigation is to create a groundwater irrigation network by taking water from bore wells.

Abstract

Kontrol selektifitas katalis alloy dua logam Ni-Ag ruah dan terembankan telah diselidiki secara sistematik dengan cara mengevaluasi pengaruh variasi rasio molar Ni/Ag, temperatur hidrotermal, waktu hidrotermal, dan pemilihan padatan pengemban yang sesuai dalam reaksi hidrogenasi selektif furfural. Rasio molar divariasi dari 0,75; 1,5; 2,0; dan 3;0, variasi temperatur hidrotermal dari 373 K, 423 K, dan 473 K selama 24 jam, sedangkan waktu hidrotermal divariasi dari 2-8 jam pada temperatur hidrotermal 523 K. Empat jenis padatan pengemban yang berbeda yaitu titanium oksida (TiO2), karbon aktif (C), gamma-alumina (g-Al2O3), dan aluminium hidroksida (AlOH) telah digunakan untuk katalis alloy Ni-Ag(3.0). Katalis Ni-Ag dengan rasio molar Ni/Ag = 1,5 dan 3,0 memiliki aktifitas dan selektifitas yang paling baik dalam reaksi hidrogenasi furfural menjadi furfuril alkoho dan tetrahidrofurfuril alkohol. Kenaikan temperatur hidrotermal dalam proses sintesis katalis Ni-Ag dan perubahan waktu hidrotermal untuk temperatur 523 K tidak secara signifikan meningkatkan kinerja katalis Ni-Ag(1,5) untuk reaksi yang sama. Katalis Ni-Ag(3.0) yang termbankan pada TiO2 memiliki aktifitas dan selektifitas yang superior dibandingkan dengan ruah dan pengemban yang lain.
